IMPROVEMENT IN STEAM-TRAPS.

'l'he Schedule referred to in these Lettori Patent and making plrl: o! the same.

Toftll whom z' t may concern Be it known that I, SETH D. Terre, of Lynn, in the county of Essex andA State of Massachusetts, have invented a new and improved Steam-Trap; and I do hereby declare that the followingis a full, clear, and exact description thereof', which will enable others skilled in the art to make anduse the same, reference being had to the accompanying drawing forming part of' this specification.

This invent-ion relates to improvements in traps for. the escape of the water of condensation in steam? heat-ing and other pipes, and consists in an arrangement ot' a receiving vessel into which the wat-cr is allowed toiiow, on a weighted balance-beam, and with a valve at the bottoni opening inward, which will be opened, when the weight of the water carries the vessel down, by the stem which projects through the discharge-tube ot' the vessel coming into contact with any suitable stop to prevent the valve going down with the vessel, but which will resume its position on the valve-seat after the discharge of the water, when, by reason of the superior' gravity ofthe weicht, the vessel is raised again.

'lhe drawing is a side view oi' in v improved trap, partly sectioned.

A isl the hollow water-receiving vessel, which I prefer to make spherical, but which may be ot any approved form. It is lsuspended from the short arm ot' a. weighted balance-bemin, B, mounted on a p'ost, C, of a stand, D, whereon is suitably placed a vertical hollow stud, E, having a lateral escape opening, F.

G is the walter-pipe entering the vessel `at the top, and designed to extend in a lateral direction, before connection with the steam-pipe, such a distance as to admit the end connected to the vessel A to rise' and fall with the said vessel without ofering material resistance to such movement'.

H is the escape-pipe leading from the lbottom of the vessel A and enteringr at the lower end the hollow stud E.

The top of this pipe is fitted for the seat ot'a' valve, I, the stem K of which is slightly longer than the pipe H, and projects through the bottom of' the same into the space in the hollow stud E.

W'hen the water of condensation fills thc 'vessel A, the gravity ofthe latter and the water will be greater than that f the weight, and the vessel will go down so that the stem K, striking the bottom ot' the space on' the stud Ewill prevent the valve from going down asA far as the pipe does, consequently, opening the valve and allowing the water to escape, after which, the vessel being relieved of' the weight of the water, will b e raised again, and the valve vwill be 'restored to its seat, closing the escape-passage against the loss ot` the steam.

Those familiar with the operation ot' steam-valves will readily perceive that there are three advantages obtained by this construction My steam-trap is suspended from a weighted lever' which will never vary in its action, while a spring would become relaxed by hea-t, open the valve when not covered by Water,and sometimes allow the steam itself` to escape.

` The valve l, having its seat located some distance above the bottom of water-chamber, allows room for the settlement by gravity of the scale and sediment, and thus obviates any liability on the part ofthe valve to choke.

The hollow sleeve H, in whose upper end is formed the valve-seat, having its lower part in the' hollow stud E, is thus guided with unerring certainty in its vertical movement, and is thus also made to convey thewat-er with perfect accuracy to the narrow ehan` nel l".

l alnaware that the principle involved in opening and closing a valve to regulate the level of water in a vessel by means of the water itself and a balanceweight or springis not new. Boilers have been constructed to exhibit the former, and steam-trapsthe latter'.

What I do esteem to .be my invention, and desire to protect by Letters Patent, is-V l. An improved steam-trap,consisting of a weighted lever, B, fulcrumed on post C, a vessel, A, having valve and valve-seat H I K attached thereto, and a vertical hollow guide, E, having outlet F therein, all supported upon the same stand I), as shown and described.

2. The spherical water-vessel and thesleeve H, havingvalveseat located above the bottom thereof',

combined 'and arranged as and for thc purpose specified. A

3. The combination of the valve-seat tube H with the vertical hollow stud E, having outlet F therein, when applied to a steam-trap, as and for the purpose specified.
